LTC6652
t ypical perForMance characteristics Characteristic curves are similar for most LTC6652s. Curves from the LTC6652-1.25, LTC6652-2.5 and the LTC6652-5 represent the extremes and typical of the voltage options. Characteristic curves for other output voltages fall between these curves and can be estimated based on their output. 2.5V Low Frequency 0.1Hz to 2.5V Output Voltage Noise 10Hz Transient Noise Spectrum
